< PRECAUTION >[VQ25DE, VQ35DE]
PRECAUTIONS
CAUTION:
 Always turn the ignition switch OFF and disconnect the negative battery cable before any repair or
inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will cause
the MI to illuminate.
 Always connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to illuminate due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
 Certain systems and components, especially those related to OBD, may use a new style slide-lock-
ing type harness connector. For description and how to disconnect, refer to PG-96, "
Description".
 Always to route and secure the harnesses properly after work. The interference of the harness with a
bracket, etc. may cause the MI to illuminate due to the short circuit.
 Always connect rubber tubes properly after work. A misconnected or disconnected rubber tube may
cause the MI to illuminate due to the malfunction of the EVAP system or fuel injection system, etc.
 Always erase the unnecessary malfunction information (repairs completed) from the ECM and TCM
(Transmission control module) before returning the vehicle to the customer.
General PrecautionsINFOID:0000000003856881
Always use a 12 volt battery as power source.
Never attempt to disconnect battery cables while engine is
running.
Before connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect negative bat-
tery cable. Failure to do so may damage the ECM because
battery voltage is applied to ECM even if ignition switch is
turned OFF.
Before removing parts, turn ignition switch OFF and then dis-
connect battery ground cable.
Never disassemble ECM.
If a battery cable is disconnected, the memory will return to the ECM value.
The ECM will now start to self-control at its initial value. Thus, engine operation can vary slightly in
this case. However, this is not an indication of a malfunction. Never replace parts because of a slight
variation.
If the battery is disconnected, the following emission-related diagnostic information will be lost
within 24 hours.
-Diagnostic trouble codes
-1st trip diagnostic trouble codes
-Freeze frame data
-1st trip freeze frame data
-System readiness test (SRT) codes
-Test values
When connecting ECM harness connector, fasten (B) it
securely with a lever (1) as far as it will go as shown in the fig-
ure.

When connecting or disconnecting pin connectors into or
from ECM, never damage pin terminals (bends or break).
Check that there are not any bends or breaks on ECM pin ter-
minal, when connecting pin connectors.
Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge) volt-
age to develop in coil and condenser, thus resulting in dam-
age to ICs.
Keep engine control system harness at least 10 cm (4 in) away
from adjacent harness, to prevent engine control system mal-
functions due to receiving external noise, degraded operation
of ICs, etc.
Keep engine control system parts and harness dry.
Before replacing ECM, perform ECM Terminals and Reference
Value inspection and check ECM functions properly. Refer to
EC-357, "
Reference Value".
Handle mass air flow sensor carefully to avoid damage.
Never clean mass air flow sensor with any type of detergent.
Never disassemble electric throttle control actuator.
Even a slight leak in the air intake system can cause serious
incidents.
Never shock or jar the camshaft position sensor (PHASE),
crankshaft position sensor (POS).
After performing each TROUBLE DIAGNOSIS, perform DTC
Confirmation Procedure or Component Function Check.
The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Component Func-
tion Check should be a good result if the repair is completed.

then slide it (C) by tapping on the side as shown in the figure.
 In areas where the seal cutter [SST: KV10111100 (J37228)] is diffi-
cult to use, use a plastic hammer to lightly tap the parts, to remove
it.
CAUTION:
If for some unavoidable reason tool such as a screwdriver is
used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper (A), remove old liquid gasket adhering to the
gasket application surface and the mating surface.
 Remove liquid gasket completely from the groove of the gas-
ket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the tube presser (commercial ser-
vice tool).
Use Genuine Liquid Gasket or equivalent.
4. Apply liquid gasket without breaks to the specified location with
the specified dimensions.
 If there is a groove for liquid gasket application, apply liquid
gasket to the groove.
 As for bolt holes, normally apply liquid gasket inside the holes.
Occasionally, it should be applied outside the holes. Check to
read the text of this manual.
